Patent number: 8638703Abstract: The invention relates to a method and a device for which, for determining a routing-metric for a mesh-network, in particular according to standard IEEE 802.11s, routing messages sent in wireless mesh networks or mobile ad-hoc-networks, on various paths of source nodes, via the mesh nodes of the mesh networks to the target nodes, are evaluated in order to determine the best path for transferring data packets from source nodes to target nodes. Said nodes are battery-operated and mesh nodes are only used in the energy-saving mode as intermediate nodes of a path when this can not be prevented due to necessary connectivity in the mesh network or due to predetermined guidelines. Also, in each routing message sent from source nodes to target nodes via various paths, a plurality of bits, preferably two bits, are used for the number of mesh nodes operating in the path in the energy-saving mode or are battery-operated when the remaining bits of the routing-message are used for the path metric.Type: GrantFiled: July 14, 2009Date of Patent: January 28, 2014Assignee: Siemens Enterprise Communications GmbH & Co.

Patent number: 8638706Abstract: A communication system provides, via a single, serving Node B, scheduling information required by a user equipment (UE) to determine a start time for each Node B of multiple Node Bs with respect to a multicast, by each Node B of the multiple Node Bs, of soft combinable MBMS data.

Patent number: 8638743Abstract: Aspects are described for reducing interference in wireless systems. In a first embodiment, an uplink acknowledgment region associated with a macro cell is determined, and an assignment of uplink control resources is restricted to a region within the uplink acknowledgment region. A control signal is then transmitted to user equipment via the assignment of uplink control resources. In another embodiment, control signals are received from wireless terminals, which include desired uplink control signals associated with an access point base station, as well as interfering uplink acknowledgement signals associated with macro cells. The control signals may then be regenerated by cancelling the set of interfering signals from the control signals. The desired uplink control signals are then decoded.Type: GrantFiled: January 18, 2013Date of Patent: January 28, 2014Assignee: QUALCOMM IncorporatedInventors: Renqiu Wang, Hao Xu

Patent number: 8638745Abstract: At least some reference symbols dedicated to a particular communication device are transmitted in resource blocks allocated to other devices. This way, reference symbol assignments are not unduly restricted by other constraints placed on the boundary elements of a resource block. According to an embodiment, data and reference signals are transmitted by transmitting a resource block allocated to a first communication device. The resource block includes a plurality of resource elements, each resource element corresponding to a modulation symbol. At least one reference symbol associated with the resource block and dedicated to the first communication device is transmitted in a resource block allocated to a second communication device. On the receive side, the communication device can perform channel estimation based on reference symbols dedicated to the device that are transmitted in resource blocks allocated to the device and in resource block(s) allocated to other communication device(s).Type: GrantFiled: May 15, 2009Date of Patent: January 28, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Jiann-Ching Guey, Havish Koorapaty

Patent number: 8638746Abstract: A method and apparatus is disclosed herein for scheduling and transmission for downlink multi-user MIMO (MU-MIMO). In one embodiment, the method comprises allocating a subset of time-frequency resources in the time-frequency plane to each distinct bin class, where each bin class comprises one or more bins of user terminals across the topology, and wherein user terminals in the one or more bins of each bin class are served across the topology by the subset of time-frequency resources. The method also comprises performing joint downlink MU-MIMO transmission using a plurality of bin class-dependent wireless transmission architectures at the plurality of base stations, where one or more bin classes is associated with one of the plurality of bin class-dependent architectures, and where each of the plurality of bin class-dependent architectures use different combinations of scheduling training and MU-MIMO transmission across the topology.Type: GrantFiled: November 3, 2011Date of Patent: January 28, 2014Assignee: NTT DoCoMo, Inc.Inventors: Haralabos Papadopoulos, Sean Ramprashad, Giuseppe Caire

Patent number: 8638747Abstract: Systems and methods for providing a handoff between technologies are disclosed. An intra-technology handoff occurs where the same integrated chassis handles the session for the different access technologies. In an intra-technology handoff, the same IP address and the session can be maintained through the handoff. The mobile node can undergo a handoff without issuing a registration request in some embodiments. An inter-technology handoff occurs from one integrated chassis to another integrated chassis. The integrated chassis can preserve session and context information in a session manager and in a handoff from one access technology to another the same session manager can be chosen with the session and context information remaining intact even though the access technology has changed. The integrated chassis can provide an access technology handoff where the core network does not notice any change and applications running on or delivered to the mobile node are not effected.Type: GrantFiled: February 8, 2008Date of Patent: January 28, 2014Assignee: Cisco Technology, Inc.Inventors: Shaji E.

Patent number: 8638750Abstract: Embodiments of the present invention provide a method for creating resources, a method for deleting resources, and a network device. The method for creating resources includes: notifying, by a first network element, a second network element at network side of a process type for creating resources for a UE; and performing, by the second network element, a process for creating resources for the UE according to the process type. With the embodiments of the present invention, a problem in the prior art that the network element at network side (i.e., the second network element at network side) cannot differentiate different access requests (i.e., initial access request and access request caused by handover between access systems) and thus corresponding resources cannot be created with respect to different access requests may be overcome.Type: GrantFiled: July 27, 2009Date of Patent: January 28, 2014Assignee: Huawei Technologies Co., Ltd.Inventors: Wenfu Wu, Shanshan Wang

Patent number: 8638752Abstract: When a mobile device moves from a first QoS-aware system to a second QoS-aware system, QoS flows may or may not be moved properly. To deal with this, the mobile device requests de-allocation of flows in the second QoS-aware system, and then initiates reservation of flows in the second QoS-aware system. After this, the mobile device will know for certain which QoS flows exist in the second QoS-aware system and can behave accordingly.Type: GrantFiled: November 10, 2010Date of Patent: January 28, 2014Assignee: BlackBerry LimitedInventors: Jose Antonio Gomez Velez, Ying Jie Zhao, Abey George, David Ma, Shiva Mirzaei-Rezaei
